Half a clear breeze

Chu Xuan transmigrated to a fantasy world and became the young master of a powerful family. He was rebuked for misbehaving just because he sneezed during a banquet. As punishment, he was banished from the ancestral mansion and was relocated to a remote residence.
He did not mind the punishment at all. He just needed a spot that could allow him to be a shut-in. With the system that would allow him to grow stronger by being a shut-in, the longer he stayed indoors, the more powerful he became.
After being a shut-in for a day, he was rewarded with the Indestructible Body Technique.
After being a shut-in for a month, he was rewarded with the Immovable Mountain Technique.
After being a shut-in for a year, he was rewarded with the Yuxu Celestial Scripture and 100 years of cultivation.
After being a shut-in for 10 years, he was rewarded with the Chaotic Indestructible Body and the Bell of Chaos.
…
Chu Xuan declared, “No one can make me leave my home. I like being a shut-in!”

I Stayed At Home For A Century, When I Emerged I Was Invincible

Among the Daoyuan realm cultivators of the Divine World, only Ding Yue had won, and that was only due to the other party underestimating him.

If they fought again, the outcome would almost certainly be reversed.

The strength of Chu Xuan's disciples had increased too quickly, and they lacked combat experience, as well as mastery of the power of their Dao paths.

In comparison to the avatars of the Ancient Chaos Gods, they were on completely different levels.

Honestly, if Ding Yue and the other disciples could defeat an avatar of an Ancient Chaos God in a straight-up fight, they would be considered invincible within their realm. After all, these Ancient Chaos Gods represented the strongest experts in the chaos below the chaos supreme realm.
